[reTerminal] Show banner and freeze with RasPi OS 32bit 2023-05-03

[matsujirushi]

If reTerminal run dtoverlay=reTerminal-bridge without commenting it, it freezes when the banner is displayed.

Environment:

• Device: reTerminal 05/09/22
• OS image: Raspberry Pi OS (32-bit) 2023-05-03

Procedure:

1. Flash OS image Raspberry Pi OS (32-bit) 2023-05-03 to CM4 eMMC.
2. Change kernel architecture. (Add arm_64bit=0 in /boot/config.txt and reboot.)
3. Install the reTerminal driver.

$ git clone --depth 1 https://github.com/Seeed-Studio/seeed-linux-dtoverlays
$ cd seeed-linux-dtoverlays
$ sudo ./scripts/reTerminal.sh
$ sudo reboot

[bigbearishappy]

It seems the dts of reTerminal bridge need to update. Before that, I just remove the installation of reTerminal bridge.
One more thing.Have you tried to boot it with reterminal bridge connected?

Hi @bigbearishappy ,
Even when I connected a reTerminal E10-1, it did not start.
